Professor Neil Ferguson quit his role as a key government adviser after it emerged he had undermined social distancing rules by meeting his married lover at his home.
Government restrictions say people should only leave their homes for essential reasons, such as food shopping or delivering items to vulnerable people.
Britons are also expected to not socialise with people from other households to avoid spreading the virus.
Ferguson is not the first prominent figure to be accused of breaching the rules.
